SHOCK LOADER AND UNLOADER.

To all 'whom t may concern Be it known that I, JAMES B. Soi-rumana, acitizen of the United States, residing at Indianapolis, in the county ofMarion and State of Indiana, have invented certain new and usefulImprovements in Shock Loaders and Unloaders, of which the following is aspecification.

My present invention relates to improvements in that class of shockloaders and unloaders (hereinafter referred to as a shock loader) shownand described in my application Serial No. 367,238,ffiled April 9, 1907,and consists in certain details of construe tion and arrangement-s ofparts which simplify and render such an apparatus highly efficient anddurable.

In the accompanying drawings, which are made a part hereof, Figure 1 isa side elevation of a shock loader embodying my invention and showing acorn shock elevated thereon; Fig. 2 a rear elevation showing shocklifters swung to different positions; Fig. 3 a perspective view showingone of said lifters in normal position and another swung to liftingposition; and Fig. 4 a perspective view of my improved lifter.

Said loader consists of a portable framework, comprising suitable sills,10, and con nections, to which are secured standards, 11, connected attheir upper ends to a beam, 12, by couplings, 18, said standards, beamand connections, Aas indicated, being composed of metal to insurelightness and durability of construction, which parts are rigidlysecured together by brace rods, 14, and by which arrangement a simpleframework for the purpose is provided. Also secured to said sills byappropriate connections are bearing rods, 15, which preferably passthrough the lower ends of said standards 11, and upon which rods 15 Imount my improved shock lifters. My shock lifter comprises two members,the lower or base member having legs, 20, which are provided with feet,21, each of which has a recess, as 22, by which it may be fitted ontoone of said rods l5 so that the lifter as a whole may be swungtransversely of the loader. Said legsV 20 converge upwardly and areconnected by cross-members, 23, 24. At the upper end of said shocklifter member I pivot-ally connect,

serial No. 535,517.

by means of a bolt, 25, or otherwise, a substantially similar shocksupporting and guiding member comprising legs, 26, which straddle saidlower member, and which legs have secured thereto a shock rest, 27, ofany suitable material and formation, and beneath which shock rest is across member, 2S, which, when a lifter is in the position indicated inFig. 1 and by the dotted lines in Fig. 2, lies liush with member 24, andis held in such position by means of a suitable latch, 29, or otherwise,the lifter in entirety in this position being substantially A-shaped.Below the connecting member 23 of the lower shock lifter member I mountan auxiliary shock support, comprising a holder, 30, in which is mountedone or more prongs, 31, and which holder is preferably rotatablyconnected to member 23 by staples, 32, or otherwise.

This shock loader contemplates the employment of a number oftransversely movable shock lifters, preferably disposed in pairs mountedon bearing rods 15 and each of which draws a shock in vertical positionup over the sills or platform of the loader on opposite sides and towardthe middle thereof to centralize the load, and upon reverse movementdischarges such shocks beyond the platform and deposits them atdestination in uprightposition in substantially the same or bettercondition than they were beforeremoval from the lield. For each pair ofthese lifters I provide on beam 12 a bracket, 33, which may be formedintegrally with coupling 13, or separately therefrom. In said bracket Iplace two sheaves, 34, and preferably on the inner sides of the sills 10I mount swiveling brackets, 35, one for each lifter` and in which ismounted a sheave, 36.

As t-he cable winding mechanism, 40, forms no part of my presentinvention, it will only be referred to herein in a general way. From adrum of said winding mechanism, as usual, I run a cable, 42, one foreach shock lifter, which passes about sheave 36, thence upwardly over asheave'34 and about sheave 43 in the upper end of the shock lifter,which cable has a suitable grappling device, 44, at its end so that saidcable may be caused to encircle and grapple a shock.

By reference to Fie. 2 of the drawing it will be understood that a shocklifter, when its members are connected by means of latch 29, ispractically a single rigid A=shaped structure which may be utilized insubstantially the manner of a boom, as indicated at 50, Fig. 2, so thata shock may be suspended from the end thereof and then swung inwardlytoward the beam 12 when the lifter is brought to the position as shownat 51; and that when said lifter is disconnected at the latching pointthe upper shock guiding member assumes a vertical position as indicatedat 52.

In the operation of my improved loader a shock lifter is brought intoshock-receiving position by releasing the winding drum upon which itscable is wound, which permits the lifter to swing outwardly over thesill or bed of t-he vehicle, and, when the latch or other locking meanshcreinbefore referred to has been released, the upper member 52, F ig.2, assumes a vertical position, its outward lower movement being limitedby means of the Flexible connection, 53, and its movement at the upperside is likewise controlled by a connection, as 54C, communicatingtherewith and with the framework. Cable l2 is then drawn outsufficiently to encircle a shock and secured by the grapple all, whenthe appropriate winding drum is rotated, which causes the cable totighten about the shock and draw the same against member 52, and theco-ntinued rotation of the drum draws said cable with the lifter andshock upwardly and toward the beam 12,' during which movement the upperpivoted member of the lifter gradually laps over the lower member, sothat when it reaches the beam the lifter as a whole is in the positionindicated at 51, Fig. 2, when it is locked or latched and the structureheld rigidly together, and the upper member thus prevented from fallingoutwardly during transportation of the loader, the cable winding drum,of course, being lockedr against further rotation. When the shock isdrawn against guide member 52, the prongs 31 of the auxiliary shocksupport enter the shock, and as the latter is being drawn upwardly to acertain extent the holder 30, being pivotally mounted, gradually turnsin the direction of the raising shock, so that the prongs in thematerial are held in upwardly inclined position and thus aid insupporting and holding the shock in place and preventing it fromslipping along lthe lifter, and when said lifter is lowered and thecable released the descending shock draws said prongs downwardly intosubstantially horizontal position ready to receive another shock. Aswill be readily understood, when a shock is being deposited the liftermembers are unlocked and the cable drum released, when the shock bygravity will descend outwardly over the sides of the vehicle, the upperguiding and retaining shock member during this operation assuming andmaintaining a constant vertical position.
